they were not implemented: 

1 Pollution prevention means any pmctice that reduces or eliminates the creation of pollutants through 

increased efficiency in the use of raw materials, energy, water, or other resources. Examples include 

SUbstituting a hazardous material with a non-hazardous material, or a process change that eliminates 

the use of a hazardous material. 

2 Dragout refers to residual plating or fmishing bath solution that remains on parts or workpieces after 

they are ~oved from the tank. .
